%WARNING: Signature not found in file flash:/c850-advsecurityk9-mz.124-15.T16.bin.

[Oerlikon_NZ]

Can anyone shed any light on the following %WARNING message?  The router(Cisco 857) appears to be boot, and operate normally.

I have tried formating the flash, re-downloading and FTP uploading the image, and also tried the latest image c850-advsecurityk9-mz.124-15.T17.bin, but this warning message persists.  I know it's possible to disable the verify option, but this is bugging me.

the bug I mentioned in post below is dependant on whether Linux was used or Solaris to build the image. If Solaris was used, you want see this warning.

Hi,

That's a known bug CSCsr09040 - "verify :file" shows "Embedded hash not found" for Linux builds.

Workaround is to use the verify /md5 command to only run md5 on the file. Compare this value to the value posted on Cisco.com for the image.  

Bug is fixed starting with 12.4(22)T.

Kind Regards,
Ivan
